Configuring an IPv6 admin-scoped zone boundary
The boundary of each IPv6 admin-scoped zone is formed by ZBRs. Each admin-scoped zone maintains
a BSR, which serves a specific IPv6 multicast group range. IPv6 multicast packets (such as assert
messages and bootstrap messages) that belong to this range cannot cross the admin-scopde zone
boundary.
Perform the following configuration on routers that you want to configure as a ZBR.
To configure an admin-scoped zone boundary:
Step
1. Enter system view.
2. Enter interface view.
3. Configure an IPv6 multicast
forwarding boundary.
Configuring C-BSRs for each admin-scoped zone
In a network with administrative scoping enabled, group-range-specific BSRs are elected from C-BSRs.
C-RPs in the network send advertisement messages to the specific BSR. The BSR summarizes the
advertisement messages to form an RP-set and advertises it to all routers in the specific admin-scoped
zone. All the routers use the same Hash algorithm to get the RP address corresponding to the specific
multicast group.
You can configure the Hash mask length and C-BSR priority globally and/or in an IPv6 admin-scope
zone.
The values configured in the IPv6 admin-scoped zone have preference over the global values.
•
• If you do not configure these parameters in the IPv6 admin-scoped zone, the corresponding global
values is used.
For configuration of global C-BSR parameters, see
Perform the following configuration on the routers that you want to configure as C-BSRs in admin-scoped
zones.
To configure a C-BSR for an admin-scoped zone:
Step
1. Enter system view.
2. Enter IPv6 PIM view.
3. Configure a C-BSR for an
admin-scoped zone.
